of the producer body and a poker extending into the same and a movementof the poker toward and from the axis of the producer,

whereby a thorough stirring up or agitation of the fuel can beeli'ectcd.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification,Figure 1 is a sectional elevation of my improved producer; Fig. 2 is asimilar view, illustrating certain modifications in the construction ofthe producer and Fig. 3 is a sectional detail view on an enlargwl scaleof the construction of poker shown in Fig. 1.

In the construction shown in Fig. 1 the producer body 1 is supportedpreferabl by means oi'beams 2 to which the shell oi the producer issecured adjacent to its upper end. The producer is covered by a metalplate 3 ha vmg an opening thcrethrougl'i for the passage of fuel intothe producer said opening being normally closed by 'a bell 4-. This bellis supp rted by a weighted lever 5 in its closed position so as toprevent the discharge of coal from the receptacle (3 into which the coaldeposited by an oscillatingcup 7 which is normally in position with itspen end in line with lh'elowcr end of a "i hute S in which the coal isplaced. The

oscillation of this cup oireceptacle from position in lmc with the monthof the chute,

' is effected by any suitable means, suclras an eccentric 5) on a drivenshall. ll). By the operation of this eccentric the receptacle would beshifted to a position to deposit the coal received from the chute, intothe re ceptacle 6. While moving to this position the lower end of thechute is closed by the curvedunderside ol thc'cup or receptacle. As soonas in its return movement, the receptacle comes into line with theopening from the chute S, a projection 11 on the underside of thereceptacle will depress the belle and permit the discharge of coal intothe producer.

By properly timing the rotation of the shaft the supply of coaldelivered to the producer can be maintained at a rate uniform with thecombustion of the coal in the producer. The lower end of the body of theproducer extends down into a basin 12 adapted to contain water to sealthe lower end of the producer. This basin, in the construction shown inFig. l, is rotatably supported by any suitable means, preferably byrollers 13.

A poker 1 1 is carried by the basin 12 in such position that its upperend will extend up a suitable distance into the body of'the producer 1.It is preferred that the poker should extend up distance suliicient'toprevent an agglomeration of the highly heated ashes or unconsumedelements of the fuel, or to break such agglomeration which may occur.The melting or softening of the material, which when melted will formthe clinker, undoubtedly occurs at the hottest part of-a producer, andthe solidification to clinker forms below that point, and where theheated materials will be subjected to. the cooling efi'ecls of theblast. In the construction Shown in Fig. l the poker is supported by thebasin in a position eccentric to the axis of the producer and to theaxis c. rotation of the basin. \Vhile being carried around by the basin,the poker is shifted so that the portion within the producer will movein a (lircction at an angle to the direction in which it is carried bythe basin. \Vhile not limiting the invention in regard to the characterof movement of the portion of the poker within the producer, it ispreferred that each portion sh uld move in. the arc of' acircle havingits center eccentric to the orbit of thepokcr around the axis of theprod ucer. 1n the construction shown in Fig. l the lower end of thepoker extends down through a boss formed on the basin 12 and to itslower end is'sccurcd a pinion 16 adapted to iulcrmesh with a circularrack 17 formed in the inner peri )hery of the annular plate 18supporting the basin. As the basin isrotatcd, which may be effected byany suitable means, such for example as that shown, consisting of apower driven pinion 19 intcrmcshing with the rack 20 on the basin, thepoker will be carried around in the producer and will. also be given amotion around the axis of the portion mounted in nected to the supplypipe 38.

the basin. If the inner end of the poker be curved or bent as shown,this rotation on its axis will cause the inner end to move in the are ofa circle eccentric to the axis of the producer, while moving around theaxis of the producer. The blast pipe 21 for introducing air and steam orboth into the producer, is supported by the basin and is provided with adistributing head 22, located within the body of the producer.

The poker is made hollow as shown and a pipe 34 for introducing acooling fluid extends nearly to the upper end of the poker. In theconstruction shown in Fig. l, where the poker is carried around the axisof the producer by the rotating basin, the lower end of the pipe 84. isconnected to a disk 35 carried by the blast pipe 21 which is located atthe center of the are of rotation of the basin and poker. A groove 36 isformed in one face of this disk and is connected to the pipe leading tothe poker. A second disk 37 is loosely mounted on the blast pipe and isprovided with a groove corresponding to that in the disk 35, said groovebeing cou- These disks are held tightly in contact, and the annularpassage formed by the grooves therein forms aconnection between thesupply pipe and the pipe 34.

In the construction shown in Fig. 2, provision is made forthe rotationof the producer body itself, while the basin and the top plate 3 remainstationary. -As shown the top plate is made independent of the pro ducerbody, but a water-sealed joint 23 is formed between the top and thebody. The body of the producer supported upon posts 24, preferablythrough the medium of rollers 25 on which rests a flange 26 secured tothe producer body. While the body may be rotated by any suitable means,it is preferred to form teeth in the outer periphery of the flange 26,with which teeth a driven pinion 27 will engage. As before stated thebasin 12 in this construction is stationary and a bevel pinion 28 issecured to the lower end of the poker, said pinion intermeshing with acorresponding pinion on the shaft 29, which may be driven from the sameshaft of the pinion 27 or independent thereof. in this construction thebody of the producer is carried around the poker while the portion ofthe latter within the producer is caused to move in direction at anangle to.

the movement of the producer.

In lieu of the construction shown in Fig. 1 for effecting the automaticfeed of the coal to the producer, a rotatable receptacle 7* is mountedin the chamber 6, said receptacle being rotated by the shaft 30. Themovement of the bell to permit the coal to drop into the producer iseffected by means of an eccentric 31 on the shaft 30, having its strap32 connected to the lever 5;.

sas es It is preferred to form screw threads on the lower portion of thepoker which will tend to force the ashes up away from the hearing of thelower end of the poker in the basin and the lower portion oi. thethreaded part is formed with a lateral extension 33, which will tend tosweep the ashes out away from the poker and toward the vertical wall ofthe basin, thus facilitating the removal. of the ashes from the latterand preventing them banking up around the blast device;

in order to protect the bearing oi. the poker from ashes, a cone-shapedshield 35) may be secured to the basin and extend up around the poker toa point above the level of the vater in the basin, and an annular apron40 is secured to the poker above the shield andextends down around theshield. \Vhile itis believed that the shield and apron will exclude allashes from around the bearing of the poker one or more open ings 11 maybe formed through the bottom of the basin within the shield.

As the upper portion of the poker, espc cially that part within thehottest zone more rapidly destroyed provision is made for the renewal ofthe upper portion, which is separable from the lower portion. A suitableconstruction for this purpose is shown in Fig. 3, and consists inenlarging the upper end of the lower portion of the poker for thereception of a nipple 42 on the movable section. This nipple fitsloosely in the socket in the lower portion, and has a curved seattherein so as to maintain a tight joint and prevent the escape of anymaterial amount of coolin fluid. The removable section is provided witha flange i3 above the nipple, said flange having an angular recess inits underside for the reception of a similarly shaped boss orprojection. 44 on the lower portion of the poker.

When it is desired to renew the poker, the fuel is allowed to burn downsuiiiciently for to permit of the fuel being shoved aside to uncover thepoint of junction between the two sections. The worn-out section thendrawn up through an opening i5 in the top plate and a new section inposition. It is preferred to form a thread 46 on the removable section,of such a pitch as to :torcc the fuel or ashes upward away from thejoint between the sections. The downward thrust due to the action of thethread on the ashes will tend to hold the two sections of the okertightly together.

. 1 here the cooling fluid is discharged through a port 48 from thelower'end of a vertically arranged poker, air bubbles are apt to form inthe upper ends of the poker, preventing the cooling" fluid from contacttherewith. In order to overcome this dithculty a second tube 4:7 isarranged in the poker and extends to a point closely adjacent to theupper end oi the chamber in the the producer, and means for poker. Thispipe will serve not only for the escape of air but also as an auxiliaryoutlet for the cooling fluid.

I claim herein as my invention: 1. A gas producer having in combinationa body portion, a poker projecting upwardly into the body portion, meansfor moving one of said parts around the axis of the produccr, and meansfor introducing air within the producer, the poker extending above thepoint of entrance of the air.

2. A gas producer having in combination a body portion, a pokerprojecting upwardly into the body of the producer, means for moving oneof said parts around the axis of shifting the portion of the pokerWithin the producer in a direction at an angle tothe circle described ythe moving part. 1

3. A gas producer having in combination a body portlon, a poker proecting upwardly into the body of the producer, means for moving one ofsaid parts around the axis of the producer, and means for causing aportion of the poker within the producer to move in the arc of a circleeccentric to the axis of the producer:

4. A gas producer having in combination a body portion, a bent pokerprojecting upwardly into the body of the producer, means for moving oneof the parts around the axis of the producer and means for rotating thepoker on the axis of the lower portion.

5. A gas producer having in combination a movable body portion, meansfor rotating saidbody portion, a bent poker projecting upwardly into thebody portion and means for rotating the poker.

6. A gas producer having in combination therewith a'poker provided witha detachable section removable Without disturbing the other portion ofthe oker when the latter is in position withinthe producer.

7. A gas producer having in combination a hollow poker having an upwardinclination into the body of the producer and pr vided with a mainoutlet for the cooling fluid located at a point distant from the'innerend of the poker, means for introducing a cooling fluid into the poker,and an auxiliary discharge pipe having its inlet opening located at apoint adjacent to theinner end of the cavity in the poker.

In testlmony whereof, I have hereunto set my hand.
